I had an MRI in december due to a persistent headache which did eventually go away. My doctor told me that the report was negative. However, I needed to get all of my records for the last 6 months for an unrelated reason and when I stumbled upon the MRI report it stated "One tiny nonspecific focus on T2 signal change is seen in the left posterior frontal parietal subcortical white matter. No other foci of increased signal are identified" and the Radiologist impression stated basically the same thing, stating about the signal change but otherwise negative study. What does that mean? Is this something I should be worried about?
I would not be too concerned about a single tiny spot, as these show up frequently without any clinical significance. Since your headache has resolved, I would keep a copy of your report, and in the future, if any new neurological symptoms develop, and another MRI is done, that can be used as a baseline for comparison.
